A. Each electrical system is identified by a code.

C. Each system is identified by an electrical code.
解析：这道题考察的是英语句子的结构和逻辑关系。正确答案是A: Each electrical system is identified by a code. 这句话的意思是每个电气系统都有一个特定的代码来识别它。在英语中，主语（each electrical system）在句子中通常位于句子的开头，然后是谓语动词（is identified），接着是其他成分。在这个句子中，谓语动词是"identified"，表示识别或辨认的意思，而介词短语"by a code"说明了是通过一个代码来识别电气系统。
举个生动的例子来帮助理解：想象一下你的家里有很多不同的电器，比如电视、冰箱、洗衣机等等，每个电器都有一个独特的电气系统。为了方便管理和维护这些电器，你给每个电器都分配了一个特定的代码，这样你就可以通过这个代码来识别和区分不同的电器。这就好比每个电器都有一个身份证号码一样，通过这个号码可以准确地找到对应的电器。所以，每个电气系统都有一个特定的代码来识别它。

A. You must obtain medical help as soon as you can.
B. You must obtain medical help as more as you can.
C. You must obtain medical instructions as soon as you can.
解析：这道题目考察的是对英语句子的理解能力。正确答案是A选项：You must obtain medical help as soon as you can. 这句话的意思是“你必须尽快获得医疗帮助”。关键词是“medical aid”意思是“医疗援助”，所以正确的表达应该是“medical help”。
如果你选择B选项：You must obtain medical help as more as you can. 这句话是错误的，因为“more”是比较级，表示“更多”，在这个句子中并不合适。
如果你选择C选项：You must obtain medical instructions as soon as you can. 这句话也是错误的，因为题目中提到的是“medical aid”而不是“medical instructions”，所以这个选项也不符合题意。
